What kinds of opossums are found in this ecoregion?

Answer:
Two unusual opossums inhabit the Patagonian Steppe. One is the tiny dwarf mouse-opossum, which has a body length of only 4 inches (10 cm)! The other is the rare Patagonia opossum, so poorly known that most records of it come from the remains found in regurgitated owl pellets!
